Edit: the tuned up version I used to climb to diamond is here:

A deck I made and used (as a new player starting 5 days ago) to climb to Gold tier on both Expedition and Throne. Most of the rare crafted are the smugglers, which I was told is a very safe/useful craft for most decks anyways.
The idea of the deck is to buff your exalted/warcry/quickdraw units, making them annoying to remove. The finishing blow is often via fast spell overwhelm (Aamri's Choice or the smuggled Rampage) --- they are lethal on Red Canyon Smuggler and her double damage. Steelfang Chakram is there as your late game card --- paired with Exalted it feels pretty strong.
